This 9" diffuser disc has a normal airflow range is 0–6 cfm. Equipped with 3/4" MNPT to insert into 3/4" FPT fittings or saddles.  Single disc or multiple discs can be used with linear air pumps, piston pumps, rotary vane pumps or regenerative blowers. Ideal for many pond and lake or tank aeration. Must be weighted to keep on pond bottom, attach to stone or brick.

Practically invisible due to their dark color, these 9 inch membrane discs are engineered for extended performance. The actual disc diffuser bodies are made of high-strength polypropylene with 3/4" MNPT connections to attach to airlines, manifolds or headers. Each diffuser has an avergae of 6,600 engineered air release orifices, 20% more than some comparable models.

The special design of the matt, flexible and supple EPDM membrane, with its proprietary thickness taper, results in full utilization of the membrane surface, even at low airflow operations.

This results in improved oxygen transfer efficiency, along with maximum operational flexibility. The disc diffuser has an integral "triple" check valve to prevent fluid backflow. Resistance is about 10" H2O when clean.
